STOVE.

Specification of Letters Patent.

Patented Mar. 2l 1916.

Application filed July 15, 1915. Serial No. 39,938.

is to provide an improved cooking stove,I

having means whereby the same may be utilized to circulate heated airthrough a house or building for heating the same, without interferingrwith or retarding the baking operation, thereby dispensing with thenecessity of providing a special furnace for heating purposes.

A further object is to provide an improved stove of this characterhaving means whereby the heated air distributing or circulating meansmay be employed simultaneously with the baking operation, withoutinterfering with the latter.

A further object is to provide a stove of this character whichwill besimple, durable and cheap in construction and effective and eicient inoperation.

To the attainment of these ends and the accomplishment of other new anduseful obliects, as will appear, the invention consists in the featuresof novelty in substantially the construction, combination andarrangement of the several parts hereinafter more fully describe/,chaudclaimed and shown in H'the accompanying drawings illustrating theinvention and in which: y

Figure 1 is a vertical longitudinal sectional view of an improved stoveof this character constructed in accordance with the principles of thisinvention. Fig. 2 is a horizontal sectional view taken on line 2-2,Fig. 1. Fig. 3 is a vertical sectional view taken on line, 3*.3, Fig. 1.

Referring more particularlyv to the drawings, the numeral 10 designatesgenerally a stove which may be of any desired size and conguration andis provided with the firepot 11. having the grate 12. and a flue orchimney 123 is also provided for carrying off the products of combustionand has ap opening 11 below the oven 15. Anotheopening 1G is provided inthe flue l?) above the oven 15 and through which opening 1V the,products of combustion pass over the top of the oven when a direct draftis desired and this opening 16 is controlled by a damper 17.

ll'hen the damper 1T is closed the products of combustion will circulatearound the oven 15 within the lasing 10 and into the fine 13 through theopening 11. The oven 15 is provided with a fine or passage 18 eX-tending therearouml and this passage has an entrance 19, into whichentrance outside air is admitted through a suitable inlet 20. and thisinlet receives its source of supply from any convenient point.preferably outside of the building. The bottom of the oven l5 isprovided with a suitable opening 21 forming communication with thepassage 18 and the interior of the oven. and the rear wall 22 of theoven is provided with an opening 23 which forms communication betweenthe interior of the oven 15 and a space or passage 24 located in therear of the wall 22.

Supported in any suitable manner preferably by the rear wall 25 of thestove casing. is a heated air circulating element 26, here shown in theform of a fan, inclosed within a casing 2T and the wall 25 of the stovecasing is provided with an opening 2S. which forms communication betweenthe space 24: and the fan casing 2T, the latter being provided with anoutlet 29 and which outlet may be connectedwith any suitable flue orpipe leading to the point where the heated air is to be discharged.

The fan 26 may be operated in any suitable manner, preferably by meansof a m0- tor 30 operating a drive belt 31, which latter passes overapulley 32 on the fan shaft so that when the motor is operated, the fanwill be operated and will draw outside air into the inlet passage 19,:asindicated by .the arrows in Fig. 1 to cause the air to circulate aboutthe oven 15, through the passage 18 and linto the oven 15 through theopening 21, through the oven out of the opening in the wall 22 of theoven into the space 24, and from this space through the opening 28, intothe fan casing 27 and out of the fan casing-27 through the outlet pipe28 to the point to be discharged. At the. same time, a portion of theair will be drawn into the space 21 through an opening Si?, in thebottom of the space.

The circulation of the. products of cornbustion about the oven will becontrolled by the damper 17 and it will thus be manifest that when theproducts of combustion are caused to circulate about the oven, the ovenwill be heated and the passage ofthe outside air through the oven andinto the fan casing will cause the air to be heated.

W'hen it is desired to bake and at the same f time employ the heated aircirculating means, the opening 21 is closed by a suitable closure whichmay be either in thev with a spider orweb 36, having a threaded portion37 to receive a threaded shank 38 and the closure is provided with ahandle 39 forlnanipulating it. Thus it will be seen that the bakingoperation may be performed by shutting off the circulation of theoutside air through the oven and at'thc same time the air which has beenheated by cir-l culation about the oven will be drawn into the fancasing 27, through the .opening 33.

The oven 15 is provided with a suitable doory or closure 40. a Y

With this improved construction it will be manifest that when it isdesired to use the stove for cooking purposes only, the motor '30 maybestopped, but when it is desired to use the stove as a heating mediumfor a, building, the motor may be started and the closures 34,35 removedso that a portion of the voutside air will circulate through the oven tobe more readily and quickly heated, but when it is desired to use thestove for baking purposes while the circulating means lis in operation,the openings 21, 23 are closed and the air which has been drawn into thepassages 19, 18 will be delivered to the fanl casing through the opening33. y c

--While the preferred form Vof construction and the arrangement of the`several parts' have been herein shown and described, it is to,beunderstood that various changes may be made in the details ofconstruction and in the combination and arrangement of the several partsWithout departing from the spirit 0f this invention, and while removableclosures have been shown for the openings 21, 23, it is'to be understoodthat'. the ordinary and well known dampers may be used in lieu thereof.It is also to be under-y stood that registersl may be provided in thevarious rooms of the building through which the heated air may bedischarged intor the room. f

That is claimed as new is: i In a stove, an oven therein, the back wallof which is spaced from the adjacent stovewall thereby forming achamber', an air passage extending around the oven, a constantly openport for said passage open to atmosphere, a constantly open port betweensaid chamber and said assage, a dampered port between said chamber andovenga dampered port between said oven and passage, a fan casing, aconstantly open inlet portvbetween said chamber and casing, an outlet.port forA said fan casing, whereby a constant current of heated ai;l issupplied directly from said passage t0 said fan and whereby a portion ofthe air in said passage may be directed through the oven and thence tothe fan.

In testimony whereof I have signed my naine to this specification, inthe presence of two subscribing witnesses, on this 12th day of July A.D. 1915.
